Units of measure have been around for a long time because they make it much easier to compare similar items.

The list of systems and units used to measure different elements is endless. There are different units of measurement that refer to distances, weights, clothing, paper measurements, memory capacity of electronic devices, and many more.

The fact that there are so many of them sometimes makes it difficult to remember how they relate to each other and how they compare.

For example, in the case of the memory capacity of electronic devices, a question may arise: **Is a GB or a TB bigger?**

For some people this question does not make any sense since we have seen the memory of devices grow from the 1.4 MB floppy disks that appeared in the early 80’s to the present day where there are hard disks of several TB (Terabytes).

Although we will go into more detail below, to save you from reading on, and answer your question:

### Is GB bigger than TB?

A GB is smaller than a TB, specifically a Terabyte (TB) is 1024 Gigabytes (GB) using the Binary system.

If you use the Decimal base system, then 1TB is 1000 GB.

**What is the relationship between a Gigabyte and a Terabyte?**

In computing and in the digital world there is a number that stands out above the rest and this is the number 2.

Digitization is based on a binary system (zeros and ones) so any unit of digital measurement will always be based on the number 2.

A GB and a TB are two consecutive units of measurement when measuring memory capacity, so 1 Terabyte is 2^{10} Gigabytes.

**How many bytes is a GB**

A Gigabyte (GB) is equivalent to 1.073.741.824 bytes (2^{30} bytes) when the Binary system is used or 1.000.000.000 bytes (10^{9} bytes) using the Decimal system.

**How many bytes is a TB**

A Terabyte (TB) is equivalent to 1.099.511.627.776 bytes (2^{40} bytes) using the Binary system or 1.000.000.000.000 bytes (10^{12} bytes) if the system used is the Decimal one.

## Digital Information Units comparison table. Where is the GB and TB in the table?

Byte | Kilobyte | Megabyte | Gigabyte | Terabyte |

1024 bytes | 1024 kB | 1024 MB | 1024 GB | |

2^{0 }bytes | 2^{10 }bytes | 2^{20 }bytes | 2^{30 }bytes | 2^{40 }bytes |

10^{0} bytes | 10^{3} bytes | 10^{6} bytes | 10^{9} bytes | 10^{12} bytes |

**What is bigger, GB or TB?**

As we have seen, a Gigabyte (GB) is smaller than a Terabyte (TB). A Gigabyte is the third unit of measurement above the minimum memory unit used to measure memory capacity of electronic devices which is the byte and in the case of the Terabyte is the fourth and therefore bigger.
